Among the various instruments which have been developed for performing post-landing experiments on the lunar surface from an unmanned spacecraft are several that provide means for observing how the lunar material responds to applied stresses. These include: penetration-hardness gages; soil-mechanics test apparatus; a subsurface-sampling rock drill; a surface-sample collector. The design and operating features and the range of application of each of these four devices are reviewed in this paper.
